Our last post on SLS in a synthetic shampoo has set the cat among the pigeons. We have received a huge number of emails, calls and messages from You stating your concern on the issue ( and you should be concerned!).
We’ve also had several of our consumers sending us pictures of the labels of their current brand of shampoo – and we’ve played Sherlock decoding the labels to them. Almost every brand of “natural” or gentle shampoo label that has been sent to us contained Sodium Laureth sulphate (SLES), that we write about and some other toxic animals like Methyl and Propyl Paraben.
And that is the point of this post. If you thought the only villains hiding in your shampoo were SLS, SLeS and silicones like DiMethicone, well, you were mistaken, weren’t you.
Instead your Shampoo has an entire secret society of villains hiding in it – (yes, we love DC Comics and aren’t ashamed of it !)
If SLS was the Lex Luthor in your shampoo, meet The Wizard, Gorilla Grodd, and the Funky Flashman, right here.
MEA, DEA and TEA (Monethanolamine, Diethanolamine and Tri-ethanolamine)
DEA, TEA and EA (Ethanolamine) are produced when aqueous ammonia reacts with ethylene dioxide.
Ethanolamines are clear, colorless, viscous liquids which reduce the surface tension of oil and water combined products so that the oil and water can mix together without separating. Ethanolamines are found therefore in shampoos, face washes, body washes, bubble baths and gels, sunscreens, hair dyes, eyeliners, mascaras and also in dishwashing detergents, liquid detergents, metalworking fluids, paints and printing inks.
TEA is commonly used in cleansing milks or creams – because it is so strongly alkaline (a 1% solution of TEA has a pH of 10), it is used as a dirt remover in ironically named “gentle cleansing creams”.
What the Industry says about MEA, DEA and TEA – rinse fast, and thoroughly:
Even industry supported and funded bodies like the cosmetics Ingredient review Panel (established in 1976 by the Cosmetic, Toiletry and Fragrance association and supported by the U.S FDA), recommended that TEA and DEA concentrations should not exceed 5%.
They also recommend that if you use a product containing any Ethanolamine, you should use the product briefly, and not continually and thoroughly scrub and rinse to ensure there is no ethanolamine lingering on your skin or scalp.
This recommendation does not take into account the fact that most of us linger when we use wash off products (and definitely more than the recommended 5 minutes). It also does not address the issue of continuous usage – many of us have now graduated to shampooing every single day. Nor does it answer the concern of DEA in leave on products like conditioners, and skin care products like mascara or even medicine like ear drops which are supposed to linger.
Why you should keep away from MEA, DEA and TEA
Effect on hair:
The excessive use of shampoos containing TEA and DEA can irritate your scalp, make your hair feel dry and lifeless, and breakdown your hair’s keratin structure,
3 studies spaced several years apart found that TEA based products occasionally cause contact dermatitis – the products studies were as diverse as a sunscreen, and ear drops.
When TEA hits water bodies, as is common when the shampoo we use goes down our drains, into our sewers and into our rivers, it can potentially cause acute and chronic toxicity in several aquatic species.
The last word on TEA:
TEA is a scheduled chemical listed in Schedule 3, Part B of the chemical Weapons Convention. This Control treaty outlaws the production or stockpiling of dangerous chemicals or their precursors that can be use to create chemical weapons.
So if we manufactured or used more than 30 tonnes of TEA every year, we have to declare this, and allow ourselves to be inspected just to make sure we weren’t manufacturing weapons. And we cannot export TEA to countries who have not signed off on the Chemical weapons Convention treaty.
Not so Fun fact: TEA is used to manufacture Nitrogen Mustard a chemical warfare weapon. In World War 2, several countries manufactured and stockpiled Nitrogen Mustard but did not use it (thankfully!). Nitrogen Mustard has a strong cytotoxic (cell destroying) effect and is today used in cancer chemotherapy.
Krya WTF moment: What the fish is a chemical scheduled under the chemical Weapons Treaty doing in your shampoo / sunscreen /shaving cream / ear drops?
Here are some avatars of Ethanolamines you could find in synthetic products around your home – our recommendation? Toss em out:
- Cocamide DEA
- Cocamide MEA
- DEA-Cetyl Phosphate
- DEA Oleth-3 Phosphate
- Linoleamide MEA
- Lauramide DEA
- Myristamide DEA
- Stearamide MEA
- Oleamide DEA
- TEA-Lauryl Sulfate
Parabens are a class of synthetic preservatives widely used in cosmetics, personal care products and medicines. They have been used in these products for about a hundred years now and are the industry standard for anti bacterial and anti fungal properties.
You can find Parabens in almost every single synthetic cosmetic and personal care product from shampoos, to skin creams to under arm deodorants. They are also used in fragrances, but as fragrances are considered trade secrets, manufacturers do not have to disclose what goes into their fragrances, including deadly villains like Parabens.
What the Industry and Governments say about Parabens:
In spite of extensive literature on the hormonal effects of Parabens, the 2006 Cosmetic Industry Review compendium trivializes the problem. They maintain that Parabens “must certainly be considered safe”.
However, after the work of many consumer awareness groups like EWG, companies like Johnson & Johnson pledged to remove both parabens and formaldehyde from its baby care and adult skin care products by 2015 including brands like Aveeno & Neutrogena.
Globally most governments have not re-examined the safety of parabens. Some outliers are the Danish government which has banned the use of products for children below 3 years. In India parabens are commonly used in cosmetic and other applications.
Why you should keep away from Paraben containing products:
Effect on skin and Hair – aging and cell damage
The irony is not lost on us. Parabens are commonly found in anti aging products. However, research shows that they actually accelerate the skin aging process!
Researchers from Meijo University, Japan concluded that Methyl Paraben could cause carcinogenic skin damage when people who used the compound in skin care products were exposed to sunlight irradiation. Similarly, Researchers from Kyoto Prefectural University of Medicine, Japan concluded that UVB exposure to Methyl Paraben when used on skin significantly increased cell death and oxidative stress in human skin.
Endocrine disrupting function
The European Commission on Endocrine disruption have listed Parabens as a category 1 priority substance because they easily penetrate skin, and interfere with the function of the hormones. In our body, Parabens can mimic estrogen.
Penetrative ability into the body:
Parabens have been detected in urine, serum, breast milk and seminal fluid, but the most worrying fact has been their detection in breast tissue from patients with breast cancer. In one important North American study, it was calculated that the average person is exposed to 76 mg of parabens every day, with 50 mg from cosmetics, 25 mg from pharmaceuticals and 1 mg from food.
Research from the CDC’s National Centre for Environmental Health found that the blood of over 60% of the children surveyed during the National Health and Nutrition examination survey was contaminated with more than 8 toxins including significant levels of 3 kinds of parabens.
One alarming property of parabens is their ability to enter the body through the skin, something that most people are not aware of. This has been widely studied in underarm cosmetics like deodorants and whiteners. Breast cancer research shows a higher concentration of parabens in the upper lateral breast near the armpit corresponding to the use of deodorants which contain parabens.60% of breast cancer tumors occur in the precise area where we use deodorant sprays!
An important point to note here is the route we allow to Parabens when we apply then on our skin and hair. While eating Parabens in your food is not the best thing to do, in the oral route, Parabens are metabolized better, and are less estrogenic.
However in the dermal route, we allow Parabens to directly enter our blood stream and make their way to our organ systems, increasing our exposure risk.
Effect on Male reproductive health:
In addition to Paraben’s estrogen like properties, this chemical has also been associated with interfering with the Male reproductive system. Studies report low sperm counts, and decreased levels of testosterone in Men linked to the absorption of Parabens form personal care products.
Boulder Colorado in 2008 undertook a multimillion dollar upgrade of their waste water effluent plant. Until then, intersex fish were a common sight – stimulated by the chemicals in personal care products like shampoos and pharmaceuticals like steroids, male fish across species developed female characteristics. This multimillion dollar plant has not removed the problem – however, with efficient sewage treatment, the male fish are taking slightly longer to get feminized.
Krya WTF moment: What the fish (pun intended) is a gender bender chemical that has been found in cancerous breast tumors, decreases sperm count and ages skin and hair doing in your shampoo? I mean, really?
Here are some labels Parabens hide under in your shampoo or skin care product:
